PRESSURE-#REGULATING VALVE FDR GAS- BURNEBS.

Speciiicationiof Letters Patent. i Patented Oct, 25, 1910.

` Application iiled April 25, 1910. Serial No. 557,472.

To all whom 'it may concern: p

Be it known .that I,'JoHN A. ABRAMS, a citizen of the United States,residing at Wadsworth, in the county of Medina and State of Ohio, haveinvented certain new and useful Improvements in Pressure-RegulatingValves forhGas-Burners; and I do declare the' lfollowing to be a full,clear,` and exact description of the invention, such as will enableothers skilled inthe art to which it appertains to make and use thesame.

This inventionrelates to improvements in automatic pressure regulatingvalves for gas burners. p

One object of the invention is to provide a regulator of this characteradapted to be applied directly tro a burner to regulate thepressure orflow of gas to the burner.

Another object is to provide a regulating valve for gas burners whichwill be simple, strong and urable in construct-ion, eiiicient, reliableand utomatic in operation andy well adapted to t e purpose for which itis designed.

\Vith these and other objects in View the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claim.

In the accompanyingdrawings: Figure 1 is a side view of a burner showingthe regulator applied thereto; Fig. 2 is an enlarged central verticalsection of the same showing the valve in open or operative position;Fig..Y 3 1s a similar view showing the valve 1n closed position; and,Fig. 4 is a horizontal section on the line 4 4 of Fig. 2.

In the embodiment of the invention I pro'- vide a casing l'formed in twosections which are bolted together around their edges as shown at 2. Inthe center of the upper section is formed a gas discharge passage 3surrounded by` an upwardly `projecting` threaded ni ple 4 with which theburner 5 is connecte In the center of the lower section of the casing isformed a depression 6 on the outer side of which is arranged adownwardly projectin interiorly threaded coupling 7 which is atdapted tobe, screwed onto the bracket or other form of gas fixture. In thedepression 6 Within the coupling 7 is formed 'a series of gas inletpassages 8.

Secured to the inner face of the bottom of the 'lower section ofthecasing around the edge of the depression 6' and covering said depressionis a small diaphragm 9 in the center of which is secured one member of agas valve said memberbeing preferably constructed in the form of a shorttube 10 the lower end of which is adapted to be engaged with anddisengaged from the stationary member of the valve said member being fpreferably in the form of a cone 11 which is secured to the center ofthe depression 6 and projects upwardly therein as shown. On the upperend of thecone 11 is formed a guide pin 12 which projects upwardly intothe tube 10 and serves as a guide for said tube. Byfarranging thediaphragm 9 over the ,depressed portion of the lower section.

of the casing said depressed portion' forms a gas inlet chamber 13 intowhich the gas passes through the apertures 8 in the bot-- tom of thedepression. The pressure of the gas in the chamber 13 will act on thediaphragm 9 causing the same to raise the tubular portion 10 of thevalve thus permitting the gas from the chamber 13 to pass into the upperportion of the casing and from thence to the burner.

Arranged between the two sections of the casing 1 and secured at itsouter edges be. tween the edges of said sections4 is a dia'- phragm 14through the center of which the tubular member 10 of thevalve projects.The diaphragm 14 is secured to the tubular member lOof the-valve and tosaid member below the central portion of the diaphragm is also securedan annular diaphragm supporting and bracing plate 15 which engages andbraces the under-side of the diaphragm 14. On the tubular member of thevalve 10 between the plate 15 and the diaphragm 9 is arranged a spacingwasher 16. The diaphragln 14 when arranged as herein shown and describedseparates the upper. portion of the casing into a gas receiving chamber17- into which .the gas enters after passing through .the valve and fromwhence the as passes to the burner as hereinbefore escribed.- ByIthusfarranging the diaphragm 14 and connecting the same with the tubuar portion of the valve saiddiaphra will ,close the valve when the gasin the c amber overcomes the pressure of the gas in the chamber. 13 thevalve will be closed b the diaphragm 14 in the manner describe It willbe noted that the diaphragm 14 has a much greater area or workingsurface than the diaphragm 9 this 'difference in the area of thediaphragms being necessary to compensate for the highpressure of gas inthe chamber 13. In one side ofthe lower portion of the casing betweenthe diaphra ms 9 and 14 is arranged an air vent or re ief port 18 whichprevents the accumulation of air in the space between the diaphragmswhich would interfere with the proper working of the same.

By means of a regulator constructed as herein shown and described itwill be seen that the iow of gas may be regulated at each individualburner and that so much gas as can be readily consumedby the burner is vallowed to pass thereto.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention as defined in theappended claim.

ymember whereb the valve is opened by the pressure of gas in saidchamber, a guide pin on said stationary member adapted to engage andguide said movable valve member, a diaphragm arranged in said casing andoperatively connected with said movable member of the valve, saiddiaphragm forming a chamber adapted to receive the gas passing throughsaid valve, said diaphragm being y adapted to close said valve when thepressure and accumulation of gas in said chamber is greater than theconsumption thereof at the burner.

In testimony whereof I have hereunto s etmy hand in presence of twosubscribing witnesses.
